[1.4.0] - 2019-10-19 ¶

Features ¶

• Added the ability to configure the number of Sanic worker processes in the HTTP server (rasa.server) and input channel server (rasa.core.agent.handle_channels()). The number of workers can be set using the environment variable SANIC_WORKERS (default: 1). A value of >1 is allowed only in combination with RedisLockStore as the lock store.

• Botframework channel can handle uploaded files in UserMessage metadata.

• Added data validator that checks there is no duplicated example data across multiples intents

Improvements ¶

• Unknown sections in markdown format (NLU data) are not ignored anymore, but instead an error is raised.

[1.3.4] - 2019-09-20 ¶

Features ¶

• Added the ability to set the backlog parameter in Sanics run() method using the SANIC_BACKLOG environment variable. This parameter sets the number of unaccepted connections the server allows before refusing new connections. A default value of 100 is used if the variable is not set.

• Status endpoint (/status) now also returns the number of training processes currently running

Bugfixes ¶

• Added the ability to properly deal with spaCy Doc-objects created on empty strings as discussed here. Only training samples that actually bear content are sent to self.nlp.pipe for every given attribute. Non-content-bearing samples are converted to empty Doc-objects. The resulting lists are merged with their preserved order and properly returned.

• asyncio warnings are now only printed if the callback takes more than 100ms (up from 1ms).

• agent.load_model_from_server no longer affects logging.

Improvements ¶

• The endpoint POST /model/train no longer supports specifying an output directory for the trained model using the field out. Instead you can choose whether you want to save the trained model in the default model directory (models) (default behavior) or in a temporary directory by specifying the save_to_default_model_directory field in the training request.

[1.3.3] - 2019-09-13 ¶

Bugfixes ¶

• Policy ensemble no longer incorrectly wrings “missing mapping policy” when mapping policy is present.

• “text” from utter_custom_json now correctly saved to tracker when using telegram channel

Deprecations and Removals ¶

• Removed computation of intent_spacy_doc. As a result, none of the spacy components process intents now.

[1.3.2] - 2019-09-10 ¶

• softmax starspace loss for both EmbeddingPolicy and EmbeddingIntentClassifier

• balanced batching strategy for both EmbeddingPolicy and EmbeddingIntentClassifier

• New type of training data file in NLU which stores response phrases for response selection task.

• Add flag intent_split_symbol and intent_tokenization_flag to all WhitespaceTokenizer, JiebaTokenizer and SpacyTokenizer

• pika keeps a single connection open, instead of open and closing on each incoming event

• RasaChatInput fetches the public key from the Rasa X API. The key is used to decode the bearer token containing the conversation ID. This requires rasa-x>=0.20.2.

• more specific exception message when loading custom components depending on whether component’s path or class name is invalid or can’t be found in the global namespace

• change priorities so that the MemoizationPolicy has higher priority than the MappingPolicy

• substitute LSTM with Transformer in EmbeddingPolicy

• defaults parameters and architectures for both EmbeddingPolicy and EmbeddingIntentClassifier are changed (this is a breaking change)

• evaluation of NER does not include ‘no-entity’ anymore

• --successes for rasa test nlu is now boolean values. If set incorrect/successful predictions are saved in a file.

• --errors is renamed to --no-errors and is now a boolean value. By default incorrect predictions are saved in a file. If --no-errors is set predictions are not written to a file.

• Remove label_tokenization_flag and label_split_symbol from EmbeddingIntentClassifier. Instead move these parameters to Tokenizers.

• Process features of all attributes of a message, i.e. - text, intent and response inside the respective component itself. For e.g. - intent of a message is now tokenized inside the tokenizer itself.

• Deprecate as_markdown and as_json in favour of nlu_as_markdown and nlu_as_json respectively.

• pin python-engineio >= 3.9.3

• update python-socketio req to >= 4.3.1

Bugfixes ¶

• rasa test nlu with a folder of configuration files

• for interactive learning only include manually annotated and ner_crf entities in nlu export

• made message_id an additional argument to interpreter.parse

• changed removing punctuation logic in WhitespaceTokenizer

• training_processes in the Rasa NLU data router have been renamed to worker_processes

• created a common utils package rasa.utils for nlu and core, common methods like read_yaml moved there

• removed --num_threads from run command (server will be asynchronous but running in a single thread)

• the _check_token() method in RasaChat now authenticates against /auth/verify instead of /user

• removed --pre_load from run command (Rasa NLU server will just have a maximum of one model and that model will be loaded by default)

• changed file format of a stored trained model from the Rasa NLU server to tar.gz

• train command uses fallback config if an invalid config is given

• test command now compares multiple models if a list of model files is provided for the argument --model

• Merged rasa.core and rasa.nlu server into a single server. See swagger file in docs/_static/spec/server.yaml for available endpoints.

• utter_custom_message() method in rasa_core_sdk has been renamed to utter_elements()

• updated dependencies. as part of this, models for spacy need to be reinstalled for 2.1 (from 2.0)

• make sure all command line arguments for rasa test and rasa interactive are actually used, removed arguments that were not used at all (e.g. --core for rasa test)

Deprecations and Removals ¶

• removed possibility to execute python -m rasa_core.train etc. (e.g. scripts in rasa.core and rasa.nlu). Use the CLI for rasa instead, e.g. rasa train core.

• removed _sklearn_numpy_warning_fix from the SklearnIntentClassifier

• removed Dispatcher class from core

• removed projects: the Rasa NLU server now has a maximum of one model at a time loaded.

Bugfixes ¶

• evaluating core stories with two stage fallback gave an error, trying to handle None for a policy

• the /evaluate route for the Rasa NLU server now runs evaluation in a parallel process, which prevents the currently loaded model unloading

• added missing implementation of the keys() function for the Redis Tracker Store

• in interactive learning: only updates entity values if user changes annotation

• log options from the command line interface are applied (they overwrite the environment variable)

• all message arguments (kwargs in dispatcher.utter methods, as well as template args) are now sent through to output channels

• utterance templates defined in actions are checked for existence upon training a new agent, and a warning is thrown before training if one is missing
